Icelandic singer Björk says she has had successful surgery to remove a vocal-cord polyp.

The eccentric 47-year-old singer says on her official Web site that she had been trying to tackle the problem with exercises and diets since doctors first discovered the polyp, a benign growth on either one or both of the vocal cords, several years ago.

She wrote: “Surgery rocks! . . . It’s been very satisfying to sing all them clear notes again.”

Björk said she had to stay quiet for three weeks. The singer apologized for cancelling various shows earlier this year, saying she looked forward to singing for her fans next year.
